In the mid-1800s, Scottish physicist James Maxwell thought something interesting was going on with electric fields, so he decided to assemble a set of equations that held true for all electromagnetic interactions. In this episode of Crash Course Physics, Dr. Shini talks to us about Maxwell's Equations and how important they are to our understanding of Physics. She discusses the ray model, reflection and refraction, ray diagrams, and converging and diverging lenses.

Content Standard(s):

Science SC2015 (2015) Grade: 9-12 Physics

10 ) Plan and carry out investigations that evaluate the mathematical
explanations of light as related to optical systems (e.g., reflection,
refraction, diffraction, intensity, polarization, Snell's law, the inverse
square law).

How to identify a system.

Skills:

Students are able to:

Develop an appropriate experimental procedure.

Create a data sheet.

Collect and organize experimental data.

Follow written and verbal instructions.

Make measurements using standard units.

Effectively manipulate laboratory equipment.

Work safely in collaborative lab groups.

Manipulate equations.

The behavior of light is predictable mathematically allowing the development of optical devices to improve vision macroscopically and microscopically.

AMSTI Resources:

ASIM Module: This standard is related to standard 8—waves and should be a continuation of the discussion of waves. Light is discussed in earlier grades and that learning should be reinforced. This standard does not address color but color should be included when working on this standard. This standard provides examples covering an extremely wide range of optics. In this document, emphasis was placed on refraction and reflection; however, the topics of diffraction and interference should also be considered for historical and mathematical relevance. Illuminance; Plane and Curved Mirrors; Concave Mirror; Snell's Law; Convex and Concave Lenses; Convex Lens; Polarized Filters and Meter Basics
